SIGN OBS TO BERNARD WILMSEN, OF PHILADELPHIA, PENNSYLVANIA AUTOMATIC WINDING'MECHANISM' non FRINGE romaine mncnr-rrns Original application filed January 7, 1929, Serial No. 330,866. Divided and this application filed September t 19, 1929. Serial No. 393,666. I v

Our invention relates to a new and useful automatic winding mechanism for fringe forming machines, whereby the fringe formed by said machines is automatically wound about a suitable, removable core, during the formation of the fringe and without interruption of the fringe making machine, the present application being a division of a contemporaneously pending case filed by us Serial No. 380,866 filed January 7 1929.

' Our invention further relates to a novel automatic winding 7 mechanism which is adapted to form part of and to be operated or actuated by the driving mechanism of the fringe forming machine proper, without in any way disturbing or interfering with the construction or operation of said machine, the completed fringe being wound automatically in the desired predetermined lengths and without requiring attention on the part of'the'operator. V r

To the above ends, our invention consists of a plurality of drums having grooves. or seats on the periphery thereof adapted to receive card .board' blanks or cores, means for detachably retaining said blanks in place, and driving means actuated by the drivingmechanism of the, fringe forming machine adapted to revolve said drums in timed relation to the formation of the fringe.

It further consists of novel means for simultaneously winding a pair of completed fringes upon a pair of said blanks or cores. Our invention further consists of various other novel features of construction and advantage all as hereinafter described and claimed. I i V For the purpose of illustrating our invention we have shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has-been found in practice to give satisfactory and reliable results, although it is to vbe understood that the various instrumentalities of which our invention consists can be various- 1y arranged and organized and-that our invention is not limited to the precise arrangement and organization ofthe instrumentalities as herein shown and described.

In the accompanying drawings Figure 1 represents a fragmentary plan View of a wlnding mechanism embodying our invention.

Figure 5 represents a fragmentary view in side elevation showing our novel winding machine applied to a fringe forming machine. s

Figure 6 represents a perspective view of a portion of the upper right hand end of Fig. 5 showing diagrammatically the manner of sewing and cutting the fringe. s Figure 7 represents a length. of fringe wound around the core or'blank shown in Fig. 3 by means of our novel automatic windingmechanism. g 1 T Referring to the drawings in which like reference characters indicate like parts, 1 designates the frame or table of a fringe making machine, to which is securedthe upright 2, which supportsthe horizontal brackets 3 which have the front or outer bearings 4 in which are journalled the vertical shafts 5. To 'thetable' l are secured the bearings 6 in which is .journalled the shaft 7, driven by any suitable connection, from the main drive shaft (not shown) of the fringe making machine; The shaft 7 carries the pulleys 8 over which pass the belts 9 which also pass over the pulleys 10 on the shafts 11,to revolve the latter. To the upright 2 is adjustably anddetach'ably secured the clamp 12, which has the vertical stem 13 which carries the coil spring 14, adjusted by the nut 15, to regulate the pressure of the presserfoot 16, which presses the work or fringe 17 after the latter has been cut by the cutters 18 on the shafts 19, the work being then propelled V forwardly or to the left of Figure 5, by the rollers 20 on the shafts 21 which are pro 7 vided with the pinions 22. The shafts 19 and21 are driven by suitable connections from the main driving mechanism- (not shown) of the fringe knitting machine, the parts heretofore described being fully illustrated and described in our copending application Serial No. 330,866 filed January 7, 1929.

The shafts 11 are journalled in the pendant hanger brackets 24 and carry the bevelled pinions 25 which mesh with the bevel pin ions 26 on the lower ends of the shafts 5 to revolve the :latter, the inner juxtaposed ends of the shafts 11 being journalled in the common bearing bracket 27 as seen in Figs. 1 and 2. The shafts 5 carry the drums or cylinders 28 which are revolved in the direction of the arrows a; when the shafts 11 are driven by'the pulley 10 and belt 9. To the outer surfacaofthe drums 28 are secured the semicircular'bands 30 by the rivets or the like 31,

the bands 30 being spaced from the drums 28 thus forming a curved pocket or seat 29 for receiving and engaging the lower portions 33 of the card board core or blank 34 best seen in Figs. 3 and 7.

The cores or blanks 34 are made of a flexible cheap material such as card board or the like, and are provided with the upper terminal ears35, which overhang the body of the core or blank as will'be understood from Fig. In Fig. 4 we have shown a retaining pin or clip 36 comprising the upper manipulatingor holding knob 37, the lower stem 38 and the flat spring 39, having a rounded bottom end, whereby the core, or blank 34; may be clamped to the drums 28 as will be understood from the dotted lines in Fig. 2, a pair of said pins being employed for each drum as seen'in Fig. 1.

The operation is as follows:

The cores or blanks 34 are positioned on the drums 28 with the lower portions 33 thereof engaging the pockets 29 formed between the bands 30 and the drums 28. The pins 36 are then applied to retain the core or blank 34 in a semi-cylindrical position. The fringe forming machine being started, the driving mechanism thereof drives our novel winding mechanism by the means as heretofore described to revolve the drums 28 in the direction of the arrows (0, thus winding the fringe 17 formed by the fringe formingmachine, upon the outer circumferences of the drum 28 and blanks 34. After a suflicient or predetermined length of fringe has been wound on the pair of blanks, the fringe is severed transversely whereupon the pins 36 are disengaged or pulled upwardly and the card board blanks 34 are withdrawn with the fringe 17 wound therearound and each blank with the fringe thereon straightens out so as to appear as shown in Fig. 6. The ears of the card board blanks 3a serve as handles and as abutments to prevent the upward slipping of the fringe wound therearound, the length of said card board blanks being approximately one half the circumference of the drums 28, so that when said blanks resume their normal flat position as seen in Fig. 7, the fringe 17 wound around the drums 28 is stretched taut on either side of said blanks as shown in said Fig. 7.

It will thus be seen that we have devised novel and simple means for winding the fringe formed by our novel fringe forming machines, automatically, neatly and efficiently, without any manual .labor and without in any way interfering with or affecting the "construction or operation of the fringe forming machine. It will be sufiicient- 1y understood from Fig. 6 that our novel fringe machine, forms a duplex fringe or pair of-fringes which before cutting are composed of the doubled. or U-shaped parallel tapes 40, around which the transverse filaments are wound transversely as at ll, seen at the right of Fig. (3. The line of stitching 1-2 is produced by the n edles shown diagramlnaticallyat 43 in Fig. 6 and the fringe fabric after being severed on a central median line by thecutters 1S, seen at the right of Fig. 5, and inFig. 6, appears as indicated at 17 at the left of Fig. 6 and in Figs 1 and 6, the fringe filaments falling from the horizontal position seen in Fig. 6 into substantially the vertical position seen in Fig. 5, which they assume during the winding operation.

By our novel mechanism, a pair of fringes are simultaneously and expeditiously wound on the cores or, blanks, which, when withdrawn fromthe winding drums, flatten out as seen in Fig. 7, and without further manipu ation or attention are ready for the market. We have deemed it unnecessary to describe in greater detailthe manufacture of the pair of fringes or the mechanism for propelling the latter to the winding drums or the means for actuatingthelatter as it is evident that other equivalent means may be employed if desired.

It will be seen from Fig. 2 that the bands 30 are about one-half the height of the drums 23 and that the blanks 33 when positioned in the seats 29 extend for their major portion above said seats so that the cars 35 are about coincident with the top of the drums 28, whereby he ringo when wound on said blanks will be neatly positioned thereon substantially as seen in Fig. 7.

We are aware that the invention may be embodied in other specific forms without dcparting fromthe spirit or essential attributes 'hereof, and we therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is:
